Question

I need help, don’t understand

Answer 1

The form of a polynomial is ax^2 + bx +c, so in the given equation 4x^2 + 4x +1:

a = 4

b = 4

c= 1

The formula for the discriminant is b^2 -4ac

replace the letters with the equivalent numbers and solve:

4^2 -4*4*1 = 16 - 16 = 0

The discriminant = 0.

The answer is D.
